1 – Overview
Building any structure using Amvic ICFs requires the installer to have a good
knowledge of the fundamentals of steel reinforcement. The placement of reinforcing steel. The designer should specify the lap splice type and lengths for every section
of the wall where splicing is anticipated. 8.

can only carry one tenth (1/10) of its compression strength in tension). Each cross section should show the wall heights involved for every storey. spacing and grade of steel
should be clearly marked for every storey in each wall cross section or in a
separate note on other sheets.6 of this chapter. Vertical and horizontal reinforcing steel bar sizes.
3.
2. Compressing a plain concrete cube
or cylinder requires a relatively large amount of compressive force before reaching
compression failure.

2 below show typical vertical and horizontal reinforcing patterns for
below grade and above grade applications using 8” Amvic ICF block respectively. In case of a multi-storey wall then the vertical reinforcement is placed
after the erection of each individual storey.
The design of reinforced concrete structures have been streamlined particularly over
the last century for safety as well as economic feasibility.
6.
Typically the first course of horizontal reinforcement is placed in the notches closer to
the EPS panel.
The second course of horizontal reinforcement is staggered so that it is placed in the
notch towards the center of the concrete wall.
28
. Vertical reinforcement bars are slid into place
from the top and weaved into the horizontal reinforcement and secured into the proper
place according to the project plans and specs. The fourth course is
placed in the same position as the second.
This staggered pattern of horizontal reinforcement is necessary to allow for the
vertical reinforcement to be placed from the top and weave in between the horizontal
steel bars.Part 6 – Steel Reinforcement for Walls
Technical Manual
Reinforcing steel has excellent strength in both compression and tension loads but is
more expensive than concrete.
Therefore reinforced concrete structures are typically designed by engineers such that
concrete is mainly utilized for most of the compressive forces and reinforcing steel is
utilized for all of the tensile forces and in some cases some of the compressive forces.4 – Horizontal Reinforcement
Amvic polypropylene webs are specifically designed to accommodate and secure the
horizontal reinforcing steel in place without the need to tie them.

Vertical reinforcement is placed after the Amvic ICF wall has been stacked and
completely erected. Reinforced concrete
structures have had a tremendous track record in some of the most complicated
structures including dams.1 and 6.

6.6 - Reinforcement for Wall Openings
Most walls will have window or door openings or both. Creating a wall opening in a
reinforced concrete wall creates extra stress around that opening especially at the
corners. Window and door headers also known as lintels can be subjected to
significant bending moment and shear forces depending on several factors.
Please refer to Appendix A for more details on how to handle reinforcement in wall
openings.

6.7 – Reinforcement Splicing
Steel reinforcement typically comes in 20 foot (6 meter) lengths. In such cases where
steel reinforcement is required to exceed this length, then a splice is required. The
main purpose of the splice is to transform the stresses whether tensile or compression
from one steel reinforcing bar or a group of bundled bars to another in a manner to
satisfy the governing local building/engineering codes and/or requirements of
engineering plans and specs.

Technical Manual

6.7.1 – Types of Lap Splice
For the purpose and scope of this manual we will only discuss one type of splicing
known as lap splicing.
Lap splicing is typically overlapping reinforcing steel over a certain length. The length
of the splice should be calculated according to the local building codes or by a local
engineer and specified on the project plans.
There are two main types of lap splices:
1. Contact Lap Splice – The lapped reinforcing bars MUST be in contact with
each other and secured together.

2. Non Contact Lap Splice – The reinforcing bars are allowed to be spaced at a
distance of one fifth (1/5) of the lapped length to a maximum of 150 mm or

When splicing a 10M reinforcing steel bar
which has a diameter of 11.3mm,
the minimum lapped splice length is:

When splicing a #5 reinforcing steel bar
which has a diameter of 0.625 inches,
the minimum lapped splice length is:

40 x 11.3mm = 452mm

40 x 0.625 inches = 25 inches

6.8 – Lapped Splices for Multiple Concrete Pours
When a project has more than one storey of Amvic ICF walls, it is necessary for the
installer to understand how to perform vertical reinforcement lap splices between the
different pours.
There are two options, both of which are satisfactory from an engineering/structural
standpoint.
Option 1
Extend the vertical reinforcement steel bars beyond the top level of the lower storey.
The length of the extension should be equal to the required splice length specified by
the design engineer or a minimum length of 40d (where d = diameter of smaller steel
bar being spliced). Please refer to figure 6.5 below for typical details.

Option 2
Cut the vertical reinforcement steel bars for the lower storey so that they are flush
with the top of that wall. Shortly after pouring the concrete, wet set additional vertical
reinforcing bars also known as dowels into the concrete. These should extend into the
freshly poured wall a length equal to the splice length specified by the design engineer
or a minimum length of 40d (where d = diameter of smaller steel bar being spliced).
The wet-set vertical splice reinforcing steel bars should ALSO protrude into the upper
wall by the same splice length specified by the design engineer or 40d as a minimum.

6.9 – Designing Reinforcing Steel for Walls
Determining the reinforcing steel schedule whether vertical or horizontal is a structural
engineering task which depends on many factors. This is beyond the scope of this
technical manual, however, some tools are available for the residential construction
market to assist in reinforcing steel design. The tools are explained below.

mentioned in the report which
must be adhered to.
If the particular project at hand falls outside of these limits then a local
licensed/registered engineer should be retained.

6.9.2 – United States
NAHB (National Association of
Home Builders) in association
with PCA (Portland Cement
Association) have prepared the
“Prescriptive Method for
Insulating Concrete Forms in
Residential Construction”
specifically for the ICF industry
[REF. 1].
This document contains
reinforcing steel schedules for
below grade and up to 2 storeys
above grade applications. It also
contains several lintel tables for
wall openings in different
applications. As expected, there
are limitations which must be
adhered to.

For applications that fall outside the scope of the “Prescriptive Method” a local
licensed/registered engineer should be retained.
PCA (Portland Cement Association) has prepared another tool for engineers to
assist in the design of ICF walls – “Structural Design of Insulating Concrete Form
Walls in Residential Construction” [REF. 2]. This publication explains in more
detail the engineering principles involved in design load bearing and non-load
bearing ICF walls even for walls outside the scope of “The Prescriptive Method”.

6.10 – Steel Reinforcing Bars and Jobsite Safety
Unguarded protruding steel reinforcing bars are hazardous and can result in injury
or death.
The following measures greatly reduce the hazards of exposed reinforcing steel:
• Guard all protruding ends of reinforcing steel bars with caps or wooden
troughs, or
• Bend reinforcing steel so exposed ends are no longer upright.
• When employees are working at any height above exposed rebar, fall
protection/ prevention is the first line of defense against impalement.

8.14 – Beam Pocket – Floor Joist Directly Bearing on ICF Wall
Steel beams and solid wood floor joists may be required to bear on the ICF walls
according to the plans. A beam pocket made inside the wall will have to be created as
per the following steps:
1. Establish the beam dimensions and the elevation at which it will be installed.
Use a laser level to mark the elevations on the inside of the EPS panel.
2. On one side of the wall where one end of the beam will bear, cut out an
opening from the inside and outside EPS panels. Make sure that the cut out
pieces are aligned and are larger than the actual beam size by about 1/2 inch
(13 mm) all around. This will facilitate placing the beam in place.

Figure 8.54 – Cut out opening from the inside and outside EPS panels on one side

8.15 - Final Adjustments Prior Pouring Concrete
Check corners for plumb. Reconfirm that corners are plumb. If they are not, use
additional bracing as required to plumb corners.
Straighten the walls. Set a screw at each
corner and install a taut string line around the
perimeter of the wall. Use an offset block (2x4
lumber piece) set at the corners, on the top
course of forms behind the string line using
another block of equal size as a guide to set the
wall to the string line.

Tip
Many builders prefer to lean the
center of each wall inward (toward
the bracing) by 1/4 inch or so at the
center of the wall segment. Then
immediately after the pour, the
braces are adjusted to push the
wall segment perfectly in line.

9.1 – Overview
This chapter of the manual explains some advanced installation techniques and
special flooring systems used with Amvic ICFs. The most common special
installations are included below, however, if you have a site specific situation that is
not mentioned here, please contact us for assistance.

9.2 - Short Corner Construction
Short corners (notches, bump-outs) are commonly found in residential construction.
Depending on the plan dimensions, Amvic 90° forms can be used or a special corner
detail can be constructed from straight blocks.
9.2.1 – Short corners using 90° corner blocks with a
stack Joint
A short corner can be constructed using at least
two 90° corner blocks. Refer to Appendix C
for minimum corner dimensions using this method.
Recommended steps are given below:

Important Note
Failure to brace a stack joint
adequately may lead to a
blowout during the concrete
pour. Make sure to use
additional bracing if necessary.

1. Install the first course so that the short legs on
both blocks are adjoining as illustrated in figure 9.1 below.
2. Install second and consecutive courses of corner blocks in the same manner
without alternating forms. This will create a stack joint.

3. Ensure that the stack joint is adequately braced on both sides of forms and at
every course.

9.2.3 – Short corners made of straight Amvic ICF
Corners shorter than the minimum allowed by our 90° blocks can be achieved by
using straight Amvic ICFs.
Steps in Creating a Custom Short Corner:
1. To begin, you will need a minimum of two straight Amvic forms.
2. Cut off 4, 6, 8 or 10 inches (100, 152, 203 or 254 mm) depending on which
block you are using from one foam panel on each straight block at the edge
of the form.

Figure 9.4 – Cutting foam from the end of the straight block on one EPS panel

3. Set the forms in place and glue the cut off pieces to fill the ends of the forms
to create a 90° corner.

5. Drill a 1/2 inch (13 mm) hole through the wood forms and the EPS panels
starting about 12 inches (304 mm) from footing or SOG. Insert a 3/8 inch
(9.5 mm) threaded rod through holes in the wood forms. Use plate washers
and nuts on both sides to hold the rod securely.

Appendix A – Steel Reinforcement for
Wall Openings
A1.0 - Reinforcing Steel for wall opening sides and Sill
Steel reinforcing bars is required for wall openings in reinforced concrete ICF walls
around the sides and sill (bottom of opening) for windows. Diagonal reinforcing steel
is also required at the corners of the wall openings. The main purpose of this
reinforcing steel is to resist cracks in concrete due to shrinkage and temperature.
Figures A1.1 and A1.2 below illustrates the placement of reinforcing steel accordingly;

Lintel top and bottom reinforcement must extend the proper development length
beyond the face of the opening and is indicated as (W) on the figure. The minimum
development length depends on many factors. As a rule of thumb the minimum
development length should be not less than 40 times the bar diameter and the minimum
required should not be less than 24 inches in order to use the Amvic lintel charts. Table
A1.1 gives the minimum (W) for the different reinforcing bars used in the charts.
If the wall opening is near the end of wall length and there is not enough space left for
proper development length then the lintel reinforcing bars should be bent around the
corner at 90° into the adjacent perpendicular wall.
Rebar Designation

Amvic has prepared lintel charts as a guideline for reinforcing steel requirements for
different loading conditions and spans. The following tables A1.2 and A1.3 represent
the limitations and assumptions that were used in developing the lintel charts for
Canada and the United States respectively.

A1.2 - Structural Assumptions;
The following is a list of assumptions used in the development of the Canadian and
US Lintel charts;
1. Concrete compressive strength at 28 days F'c = 20 Mpa (3000 psi).
2. Steel reinforcing bars yield strength Fy = 400 Mpa (60 ksi).
3. Lintels are considered as single span beams with fixed ends due to the fact
that the walls and lintels are monolithically cast.
4. All loads on the lintels are assumed as uniformly distributed loads. No
concentrated loads from girders or trusses were considered.
5. Maximum reinforcing bar size used is 30M for Canada or #9 for the US.
6. Maximum number of bars for top or bottom of lintels is 2. No bundled
bars were considered.
7. When the chart identifies a single reinforcing re-bar (e.g. 1-15M or 1-#5)
for top or bottom, a single C-stirrup should be used as per the charts. If
however double reinforcing bars for either top or bottom of lintel is
identified (e.g. 2-15M or 2-#5) then a double C-stirrup MUST be used.
161

Appendix A – Steel Reinforcement for Wall Openings

8. Never exchange a double reinforcing bars configuration for a single larger
size bar (e.g. don't use 1-15M or 1-#5 instead of 2-10M or 2-#4
respectively).
9. The Canadian lintel charts are based on CSA A23.3-94.
10. The US lintel charts are based on ACI 318-02.
